Hi,
I think this is just an opaque corundum. All Rubies and sapphires are from the corundum group but not vice-versa.
The seller has mentioned about IGI certification but not providing it - strange. He can provide a photo of the certificate to let the buyers check the details. I don't think IGI will ever term it as Ruby. If so, then it may be the one of the biggest ruby on sale in India, just now !!!!
Ebay must ask the seller to prove the authenticity of the listing.
